Preheat the air fryer to 375 degrees F, using the air fryer setting, preheat for 2-4 minutes. In a large bowl, combine the shredded chicken and barbecue sauce.
On a flat surface, roll out the crescent roll dough and separate it into crescent roll triangles. Spoon a heaping tablespoon of the chicken and barbecue sauce mixture onto each crescent dough triangle or rectangle shape. Sprinkle the shredded cheddar cheese and crumbled bacon over the chicken mixture.
Use a fork to seal the edges.
Spray the basket of the air fryer with cooking spray, or brush with olive oil. Place the bites in the basket of the air fryer, making sure the dough pieces are not touching, in a single layer.
Air fry the crescent rolls at 375°F for 5-6 minutes, or until they're golden brown and crispy. For added flavor, brush with melted butter during the cooking process
Remove the crescent rolls from the air fryer and let them cool for a few minutes before serving. Garnish with chopped fresh parsley, if desired.
